"Open with google chrome"

Firefox Development
1

Hi,

I recently installed Chrome on Debian 12 + XFCE. Suddenly Chrome menus appeared in Firefox, such as “Open with Google Chrome” when I right click on a downloaded pdf.

How is this even a thing? And how do I get rid of them?? I looked under Applications in about:preferences, but nothing there. I assume FF is desktop agnostic and there’s some platform independent API allowing dynamic menu manipulation, but it isn’t something I know anything about. What are the specifics?

I’ve been looking at the XFCE .desktop files, and I expect that is the mechanism in this case, but I’d like to know what the application provides to allow it to operate.

Best,
bitrat

I’m using Ubuntu 22.04.3 + XFCE and I don’t have those menus.

Are you using a Debian build of Firefox or a Mozilla build? Two options: Either Debian added the feature to Firefox or Debian by default adds an add-on to add the Open with Chrome.

For the second option you should be able to disable the add-one. For the first option you can switch to a Mozilla build of Firefox.

Please let us know what you find out.

I’m not a Linux/Debian user, but are Chrome set up as the default pdf-viewer on your system?
Maybe it is just Firefox giving you the option to open a pdf file in whatever application is set up as the default pdf-viewer on your system?

Hi Stig, thanks for that. Default application it is.

xfce4-settings-manager | System | Default Applications | Other

Set for each MIME type. No way to add new MIME type, but the list looks comprehensive.

I’m not sure there was a default before, or at least I don’t remember an application appearing in that position on the right click menu, but the settings manager doesn’t seem to allow setting the default app back to none.

Cheers

Hi B.J.,

thanks for this. I’ve solved the mystery as below, but your suggestion is something I hadn’t thought of.

What’s the best way to determine those details?

Troubleshooting info says:

Name Firefox
Version 102.14.0esr
Build ID 20230724114731
Distribution ID
User Agent Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0
OS Linux 6.1.0-10-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-2 (2023-07-27)
OS Theme Xfce / Adwaita
Application Binary /usr/lib/firefox-esr/firefox-esr

… plus a lot more.

I’m interested to know how distro builds vary, and what options might be available if I build it myself.

Cheers,
bitrat
